SUMMARY The farms dedicated to the production of rubber latex have evolved their techniques of exploitation from the storage to the commercialization of the rubber; Due to the constant research on the part of international and national institutions that strengthen the exploitation of the crop, the efficient management of a productive unit is reflected in the production yield of each one, that is why the heveiculture has penetrated in agricultural practices as is the fertilization in different parts of the tree, one of the techniques is directed to the pica panel looking to increase the production of kilograms of dry rubber per tree and unit area. The present investigation "Evaluation of four organic fertilizers applied to the Pica panel in the rubber culture Hevea brasilensis (Willd. Ex A. Juss.) Müll. Arg. In San Jose Las Victorias farm, San Andres Villa Seca, Retalhuleu "which is owned by the company El Pilar Sociedad Anonima, geographically, it is located with respect to the Greenwich meridian at the coordinates latitude 14 ° 33¨ 11.6 'and longitude 91 ° 35 ¨11.2' at an altitude of 376 meters above sea level. Five treatments, four organic fertilizers and one absolute control were evaluated, they were applied in mixture with the phytosanitary program of the farm directed to the pica panel; the research was established under an experimental random block design, with 20 experimental units of 30 rubber trees of clone IRCA-41 for each of them. The best result was 7.52 kilograms of dry rubber per year per tree when applying Biomin Phosgard (treatment two). This same product obtained the best dry rubber content (DRC) of 57.53%.
